Kinematics of machinery

It is of 2 parts.
1.kinematics of machinery
2.dynamics of machinery

Fluid Mechanics and Hydraulic machines

Fluids include liquids and gases.
Fluid mechanics is the study of how fluids move and the forces on them.
Fluid mechanics is that branch of physics which deals with the properties of fluid,namely liquid and gases,and their interaction with forces.

Heat Transfer

Heat transfer is the passage of thermal energy from a hot to a colder body. When a physical body, e.g. an object or fluid, is at a different temperature than its surroundings or another body, transfer of thermal energy, also known as heat transfer, or heat exchange, occurs in such a way that the body and the surroundings reach thermal equilibrium. Heat transfer always occurs from a hot body to a cold one, a result of the second law of thermodynamics. Where there is a temperature difference between objects in proximity, heat transfer between them can never be stopped; it can only be slowed down.

Strength of materials

The strength of a material refers to the material's ability to resist an applied force.
The term strength of materials most often refers to various methods of calculating stresses in structural members, such as beams, columns and shafts, when the equations of equilibrium are not sufficient to solve the problem.


basic terms:
Stress terms
Strength terms
Strain(deformation) terms
Stress-strain relations
Design terms

Subjects

subjects for a mechanical engineer are of 3 groups
1.design
2.production
3.thermal

1.Design:
Design is for designing machine elements. It is different for different materials.Designing forces is the first part in design. Subjects deal with designing forces are mechanics,solid mechanics,fluid mechanics,machine theory.
Machine parts are designed by using forces.Here we design bearings,shafts.......
machine design is the subject.

2.Production:
Production is for producing elements according to the design which is made by designers.
Subjects are poduction technology,instrumentation,metrology,machine tools...

3.Thermal:
here the subjects are thermal related. Thermal engineering,heat transfer,power plant engineering,refrigeration,air conditioning...........

Need of Mechanical engineers

from the past 100 years mechanicals are ruling the world.
Persons who are ruling world are ruling because of mechanicals.For this no need to give examples.Though there are some companies without mechanicals,majority are mechanicals.
You can live with out computer,you cant without power.

Now mechanicals are playing an important role in Power plants.
there several options for mechanicals in higher studies.
